Windows 7 VM freeze on Ubuntu 12.04 KVM

Bug description:
Hi,
I have recently setup a Windows 7 VM on KVM and started using it
through remote desktop.
What happens is that, after some hours of usage, the remote desktop
connection freezes. I thought it was a remmina bug, as the it was
enough to kill and restart it to successfully connect again to the VM.
However, today I've switched to a different RDP client (2X Client
chromium app) and the freeze just happened again!
Some information:
- the host and the VM are completely idle when the freeze occurs
- I've tried sniffing the network packets toward the RDP port during the freeze and found that the client is sending packets but no packet is sent back
Could this be a KVM issue? How can I further debug this one (I expect
the freeze to happen again...)?

Hi,
I reported the #1212051 (https://bugs.launchpad.net/ubuntu/+source/qemu-
kvm/+bug/1212051) bug with Windows XP, but reading this case i think it
could be the same issue.
I connect via RDP to my windows XP VM and after a while it seems to
freeze, then, I connect via VNC an without doing anything the
communications are restored between the VM and the outside world. So i
can connect again with RDP.
Even more, if i leave an open connection with VNC (minimized because is
more slow than RDP), connecting via RDP has no trouble and no problem of
freeze (lost of communications) occurs.
f3a97, Could you do this test and tell if you have the same experience than i?, If so, my bug is the same of this.
Thanks.

Hi Hector,
My network configuration is different than yours - it is not bridged.
Perhaps this might help to diagnose the issue?
I'm now trying to sniff network traffic generated by the VM and see what
happens during RDP hangs: does it still poll outside servers (i.e. google
drive) or will become disconnected?
I'll report the results, stay tuned.

Hi,
Eventually I've been able to reproduce the hang.
Just to recap the experiment: I have recorded network traffic during RDP
connection hangs. The result is that the VM has do not experience total
network loss: network traffic continues to flow (tcpdump from the host on
ports other than 3389).

Hi,
I have recently setup a Windows 7 VM on KVM and started using it through
remote desktop.
What happens is that, after some hours of usage, the remote desktop
connection freezes. I thought it was a remmina bug, as the it was enough
to kill and restart it to successfully connect again to the VM.
However, today I've switched to a different RDP client (2X Client
chromium app) and the freeze just happened again!
Some information:
- the host and the VM are completely idle when the freeze occurs
- I've tried sniffing the network packets toward the RDP port during the freeze and found that the client is sending packets but no packet is sent back
Could this be a KVM issue? How can I further debug this one (I expect
the freeze to happen again...)?

Hi f3a97, did you tried to connect via VNC when the freeze situation
occurs?
This method works as a a workaround to defreeze my windows VM.

Hi,
I have recently setup a Windows 7 VM on KVM and started using it
through remote desktop.
What happens is that, after some hours of usage, the remote desktop
connection freezes. I thought it was a remmina bug, as the it was
enough to kill and restart it to successfully connect again to the VM.

Since a couple of weeks ago, we started to reboot the VM diary. With
this way, the problem occurs very less. We have counted only twice in
this period.

I added a rtl8139c netcard to the VM and connected through it by RDP -
no more freezes.
It looks like kvm does not play well with virtio network cards and RDP.
Red Hat virtio net windows driver version: 62.65.104.6500, 6/19/2013
I left the RH adapter on the VM, I just connect via RDP through the
rtl8139c network card.

Hi,
I have recently setup a Windows 7 VM on KVM and started using it
through remote desktop.
What happens is that, after some hours of usage, the remote desktop
connection freezes. I thought it was a remmina bug, as the it was
enough to kill and restart it to successfully connect again to the VM.
However, today I've switched to a different RDP client (2X Client
chromium app) and the freeze just happened again!
Some information:
- the host and the VM are completely idle when the freeze occurs
- I've tried sniffing the network packets toward the RDP port during the freeze and found that the client is sending packets but no packet is sent back
Could this be a KVM issue? How can I further debug this one (I expect
the freeze to happen again...)?

This makes me wonder if the bug may not actually be in the virtio net driver.
The source for that is at
https://github.com/YanVugenfirer/kvm-guest-drivers-windows .
Something like commit 9b1b81a731f722efa8df24429649b527a17bf433 might
be relevant (assuming the git HEAD has this fixed, which I've not
tested).

Hi,
I've double checked my conf, I can confirm I'm not using virtio but
standard Win 7 drivers. (please see my VM conf that I posted some time ago).
So it's not definitely a virtio-specific issue.

Triaging old bug tickets... can you still reproduce this issue with the
latest version of QEMU? Or could we close this ticket nowadays?

Title:
RDP traffic freeze on quiet network
Status in QEMU:
Expired
Status in qemu-kvm package in Ubuntu:
Expired
Status in Debian:
Incomplete
Bug description:
To summarize what I think has been found so far,
1. The main symptom is that RDP connections hang after some time
2. This bug affects qemu 1.0 .. 1.6.5
3. This bug affects at least windows xp and windows 7 guests
4. Keeping another network connection open, such as vnc, prevents the RDP connection from hanging.
========================================
Hi,
I have recently setup a Windows 7 VM on KVM and started using it
through remote desktop.
What happens is that, after some hours of usage, the remote desktop
connection freezes. I thought it was a remmina bug, as the it was
enough to kill and restart it to successfully connect again to the VM.
However, today I've switched to a different RDP client (2X Client
chromium app) and the freeze just happened again!
Some information:
- the host and the VM are completely idle when the freeze occurs
- I've tried sniffing the network packets toward the RDP port during the freeze and found that the client is sending packets but no packet is sent back
Could this be a KVM issue? How can I further debug this one (I expect
the freeze to happen again...)?
